Shallow geothermal in Australia – from “cold” Melbourne to “hot” Sydney
This is the second out of three articles in shallow geothermal series. In the first one, we focused our attention on Sweden, where 100% of geo-energy is produced by shallow…

Shallow geothermal in Sweden – A deep penetration in the geo-energy market
The top three countries in terms of geothermal energy production are China, the US and Sweden. In total, these countries produced around 200 TWh in 2020. Of that figure, ground-source…
The first high-temperature aquifer thermal energy storage project in Europe
“We have a unique geothermal energy solution here”, says geologist Eva van der Voet from Ennatuurlijk Aardwarmte in Middenmeer, the Netherlands. “The complex of greenhouses we deliver energy to is…
Why Taiwan is looking at geothermal energy with a lot of interest
“Taiwan’s geothermal heat gradient, ranging from 48 to 60 degrees per kilometre, is a clear testament to the island’s volcanic origin. This natural advantage has sparked significant interest in geothermal…
Brushing up on your geothermal vocabulary
It must have been a major exercise to write the paper that was published recently by authors Maryam Khodayar and Sveinbjörn Björnsson in the Open Journal of Geology. I know…
Shallow geothermal drilling is not without risk
It is not every day that geological expertise is brought to the Supreme Court. Late last year, Norway’s highest court dealt with a claim for compensation for subsidence damage to…
A new closed-loop horizontal geothermal well solution
In Europe, deep geothermal heat production for district heating and to a lesser extent district cooling is mainly based on the conventional doublet geothermal well solution. Examples are the wells…
The deepest closed-loop borehole drilled in the UK
This is not the first time I write this, but I keep on saying it. If there is any sector in the geothermal drilling space that is active in the…
Geothermal potential of Ukraine
Ukraine has several geothermal sites and resources, especially in the Transcarpathia region and in the southern part of the country. However, the development of geothermal resources has not been extensively…
A puncture in a geothermal seal
More than fifteen years ago, Delft University of Technology (TU Delft) was one of the first institutions in the Netherlands to come up with the idea to warm their premises…
Shallow geothermal energy production may soon be more important than deep geothermal energy production in the Netherlands
It is a development that is not often talked about or highlighted in the media, but data on subsurface energy production using water as a carrier clearly shows how important…
How to explain the low energy output of one of the UK’s flagship geothermal projects?
In September last year, the UK Government announced a list of renewable energy projects that qualify for a minimum price guarantee for the energy delivered to the grid. Geothermal projects…
